Title: Fabrication of semiconductor device
Inventor: SAITOU KASUMI
IPC: H01L21/28
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of excessive erosion being generated in a conductive material film filling a contact hole made in an insulating film at the time of etching back the conductive material film. SOLUTION: At first, a contact hole 3 reaching a substrate 1 is made through an insulating film 2 and then an adhesion layer 4 is formed while covering the upper surface of the insulating film 2 and the inner surface of the contact hole 3. Subsequently, a conductive material film 5 is formed while covering the upper surface of the adhesion layer 4 and filling the contact hole 3 through the adhesion layer 4. Thereafter, the conductive material film 5 is removed close to the upper surface of the adhesion layer 4 by first etching and further removed until the upper surface of the adhesion layer 4 is exposed by second etching. The conductive material film 5 is removed while cooling the substrate 1 down to a temperature lower than a point where reaction products of an etching gas used in the second etching and the compositional material of the adhesion layer 4 is gasified.

Title: Spraying liquid for inhibiting oil discoloration of fish such as tuna and for retaining its freshness
Inventor: OHARA SABURO
IPC: A23B4/14
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a spraying liquid capable of suppressing the discoloration of a fish even at the ordinary temperature. SOLUTION: This spraying liquid for suppressing the oil discoloration and discoloration of the fatty portion of tuna or the like is obtained by adding a pH-controlling agent, an emulsifying agent and EPA.DHA to a composition comprising extracted tocopherol, vitamin C and ethanol. The spraying liquid for suppressing the oil discoloration and discoloration of the red meat of tuna or the like is also obtained by adding ethanol, a pH-controlling agent and a thickening agent to a composition comprising an amino acid, a condensed phosphate salt and vitamin C. The free radical group chain-stopping actions of the antimicrobial ethanol and tocopherol, the reduction power of the vitamin C and the buffering action of the pH-controlling agent persistently suppress the deterioration of unsaturated fatty acids causing the discoloration of the fatty meat. The spraying liquids are directly sprayed on the meat of a fish such as tuna to prevent the autoxidation of unsaturated fatty acids, and the effect can be persisted especially at the ordinary temperature.

IPC: H04M9/08
Filed: 1991-11-29
Abstract: PURPOSE: To obtain an acoustic characteristic calibration circuit and a method for judging the type of acoustic environment used in an adaptive speakerphone. CONSTITUTION: Acoustic characteristic calibration circuits 210, 213, 220 and 230 judge whether it is a deteriorated acoustic characteristic (large loom) or a fine acoustic characteristic (small room). This calibration circuits judge the acoustic environment of a room by generating tone burst in a transmitting path via a speaker 212 connected with the speakerphone 200 and generating an echo attenuating parameter showing a duration time of echo from a tone burst signal measured in a connected microphone 211. If the in-room acoustic characteristic is deteriorated, the speakerphone performs adapting by maintaining the switching response in the quantity equal to the switching response of a typical analog speakerphone.  However, if the acoustic characteristic is fine, the speed of the switching time of the speakerphone is increased, and an interrupt threshold value and the total amount of inserted switching loss are reduced.

Abstract: PURPOSE:To attain the effective use of the recording capacity by forming the next address based on the branching destination address when the arithmetic result of an arithmetic circuit which shows the satisfaction of conditions is applied to an addressing circuit at the time of execution of a conditional branching instruction. CONSTITUTION:An S5 selector 15 is provided into an addressing circuit. The selector 15 receives an SL field and value '1' from a program ROM 1 and a control logic part 3 respectively and works based on the control signal given from the part 3. In executing a condition checking/branching instruction, the SL field is selected as long as the conditions are satisfied. Then the SL field value is added to the present value of the address of a program ROM 1 via an adder 4. Thus the next address is formed to the ROM 1. Otherwise the selector 15 selects the value '1' received from the part 3 and actuates the adder 4 as a program counter. In such a constitution, the number of program steps related to the branching processing in particular can be extremely decreased.
